I am wondering how I send back a HTTP response of 501 (Not Implemented) in Lighttpd web server, when somebody tries to access our api.mydomain.com over non-ssl.

The check we have, but don't see how to actually send back the HTTP response of 501.

$HTTP["host"] =~ "api\.mydomain\.com$" {
        $HTTP["scheme"] == "http" {
                //// HOW DO WE SEND BACK HTTP RESPONSE 501

The lighttpd way:

With config file, I only know about 404 errors. To send a "non implemented" response, you may use lighttpd mod Magnet (and install LUA), then:

In the config file:

$HTTP["host"] =~ "api\.mydomain\.com$" {
        $HTTP["scheme"] == "http" {
            magnet.attract-physical-path-to = ("/path/to/501.lua")

Note that "/path/to/501.lua" should be readable by lighttpd. Then in the 501.lua file:

lighty.content = { { filename = "/path-to-your/501.html" } }
lighty.header["Content-Type"] = "text/html" 
return 501

Very hard to just send a 501... right ?

The alternative way:

If you already have a dinamic language pluged with fastcgi, etc, you can implement error responses (lets say, 501.php) that does what the .lua script makes:

  • Send the proper http response (feasible on any "web" language)
  • Print the proper headers (feasible on any "web" language)
  • Print the proper html or template or static file (feasible on any "web" language)

And use them where needed.

Ok, how about this, instead of returning 501, how do we just kill that request. Basically, I don't want users to be able to hit api.mydomain.com in non-ssl. Is there a way to just abort the HTTP request in lighttpd? –  Justin Apr 9 '11 at 19:55
try adding: url.access-deny = ("") where your comment "//// HOW DO WE SEND..." –  poisonbit Apr 10 '11 at 9:11
Yeah, that returns back 403, Forbidden. I suppose that works, anything to just drop the connection though, basically just server not found error. –  Justin Apr 10 '11 at 20:26
